Next, using the correct answer information generated from the formula, related information in which the value obtained by using the formula is associated with the component of the problem is generated.
To be stored. For example, the formula term of the correct answer information in FIG.
Since it corresponds to the items of the income statement 1602 and the balance sheet 1603, by disassembling the formula, it is possible to associate the calculated value with the component of the problem. Generate related information including the stored related items.

The learner answers the presented problem. For example, as shown in FIG. 18, when answering "management capital turnover rate" of "the previous term", "management capital turnover rate" of "the previous term" of the question and answer sheet 1701 is designated (1801),
A calculator 1704 is used to calculate and input an answer. FIG. 19 is an example of the answer created by the learner.

Items 1901 to 1904 are examples of item errors calculated using “cost of sales” where “sales” should be used. Reference numeral 1905 denotes an example of a careless miss error calculated by using “106” where “160” is to be used. 1906 is an example of a formula error in which “(current deposit / (cash deposit + trade receivables + securities))” is incorrectly applied and calculated when “(cash deposit + trade accounts + securities) / current liabilities” should be used. is there.

When the learner's answer is over, the difference between the correct answer information and the learner's answer is extracted and used as error information. For example, as shown in FIG. 20, error information including a calculated value, a learner's formula, an answer, a correct answer / incorrect answer, and an error type is extracted. The screen of the correction result is, for example, as shown in FIG. 23, in which the error portion (2301 to 2306) in the answer sheet is clearly indicated to the learner by changing the color.

If the learner issues a correction message request for the specified error portion, the correction message determination processing 10

In addition, the problem-specific place determination processing 105 determines the highlight display part in the problem display area using the “related item” of the related information.

The correction presenting process 106 presents a correction message for the erroneous portion determined in the correction message determining process 104, and changes the color of the character string to be highlighted in the problem display area determined in the problem explicit portion determining process 105. And present it to the learner. For example, if the learner
In response to the item error of the “operating profit margin” 2301 in the “previous year” of the question / answer sheet 1701, a correction message request is issued. When the rule stored in the correction message determination rule storage means 102 is the rule as shown in FIG. 22, if the correct answer rate of the learner is between 30% and less than 60%, the "correction message" of the rule in FIG. In accordance with the “highlighting of the problem”, the correction message determination processing 104 determines the correction message “the item to be used is incorrect” using the correction message of “item error” in FIG.

Further, the problem-specific place determination processing 105 uses the “related items” of the “operating profit margin” in the “previous year” of the related information. The character strings to be highlighted in the income statement 1702, here, “operating profit” and “sales” are determined.
Next, as shown in FIG. 24, the correction presentation processing 110 changes the color of the item 2401 of the profit and loss statement 1702 necessary for calculating the “operating profit margin” at the same time that the correction message 2402 is presented. And provide correction guidance.

When the learner issues a correction message request for an official error in the “early ratio” 2206 of the “first half” in the answer sheet in FIG. 25, the correct answer rate of the learner is 30% or more and less than 60%. If it is between, the correction message determination process 104 uses the correction message of “formal error” in FIG. 21 according to the “correction message” and “highlight problem” in the rule of FIG. I will. " Further, the problem clearing part determination processing 105 uses the “related items” of the “quick ratio” of the “previous year” of the related information to highlight the character string of the balance sheet 1703, here “cash deposit”, “trade receivable”. ”,“ Securities ”, and“ current liabilities ”.

Next, as shown in FIG. 25, the correction presenting process 106 presents a correction message 2502,
Balance sheet 170 required to calculate the "quick ratio"
The item 2501 of No. 3 is indicated by changing the color, and correction instruction is performed. In this way, the learner performs learning according to the presented correction.

According to the above-described method, in addition to the trouble of creating related information in the correction instruction of the calculation problem, the problem can be used directly for the correction instruction, and it is necessary in the problem to guide the correct answer. What is unnecessary and what is unnecessary can be clarified, and the understanding can be deepened.

Although the color change is used as a method of highlighting the character string in question, the character string can be clearly displayed by blinking, underlining, or the like. Although the character strings in the material are highlighted, the character strings in the question sentence can also be highlighted. Further, the information to be specified in question is a character string, but may be a voice, an image, a moving image, or the like.

The correction presentation process 106 presents to the learner the highlighted display position in the question determined in the problem explicit position determination process 105 and the message determined in the correction message determination process 104.

[0097] Taking the problem of financial processing as an example,
This will be described with reference to FIGS. 16, 17, and 32. In this example, the components of the question to be clearly shown to the learner are the items of the material. When the learner starts learning, the generated problem is presented to the learner. For example, as shown in FIG. 17, a question presentation area including a question / answer sheet 1701, a profit and loss statement 1702, and a balance sheet 1703, and a calculator 1704.
Is presented to the learner.

As in the second embodiment, using the correct answer information generated from the formula, related information in which the value obtained by using the formula is associated with the component of the question is generated and stored in the correct answer related information storage means 103. .

The learner answers the presented problem. For example, as shown in FIG. 32, the learner clicks on the “previous year” “operating profit ratio of operating capital” 3201 of the answer sheet with a mouse in order to input the answer of “operating profit ratio of operating capital” of “previous year”. Answer input event reception processing 2601
Accepts a mouse click as an answer input event, judges that the question the learner is trying to derive is the “operating profit margin” in the “previous term”, and uses “ The operating profit ratio of management capital is passed to the problem-specific place determination processing 105. The problem-specific place determination processing 105 uses the “input margin” of the “previous year”, which is the answer input event information, and the “related items” of the related information in FIG. 15, and highlights the income statement and the balance sheet. Determine the strings "Operating income", "Current assets", "Depreciable assets", and "Land". Since it is not in the "Intangible fixed assets" document, it is not a character string to be highlighted.

The correction message determination processing 104 is, for example, "Let's see the problem well" stored in the correction message storage means 101 when an answer input event is received.
If there is a rule that issues a correction message, the correction message "Let's look at the problem carefully." Is determined according to the rule. In the correction display process 106, as shown in FIG. 32, at the same time that the correction message 3203 is presented, the item 3202 of the profit and loss statement and the balance sheet necessary for deriving the correct answer to the problem solved by the learner is changed in color. , And provide correction guidance.

With the above-described method, in the correction instruction of the calculation problem, when the answer is prepared by the learner, the item in the question which is the point of the calculation is presented, and the learner becomes a hint in preparing the answer.

Note that the color change is used as a method of highlighting the character string in question, but it is also possible to make it clear by blinking or underlining. Although only the character strings in the material are specified, the character strings in the question sentence can also be specified.

When an answer input event is received,
Although the character string in question is highlighted, the character string in question may or may not be highlighted according to a certain rule, for example, a learning situation or difficulty. Further, the character string in question can be highlighted in response to a request from the learner, for example, in response to a request for a hint. Further, the information to be highlighted in the question is a character string, but may be a sound, an image, a moving image, or the like.

[0090]

As described above, according to the present invention, first, by highlighting points that are important for deriving a correct answer in a question, it is possible to determine at a glance which part in the question is an important point. Understand and provide effective learning guidance.

Secondly, in addition to eliminating the trouble of creating related information, necessary and unnecessary items can be seen at a glance by highlighting items used in formulas for deriving a correct answer in a question. Understand and provide effective learning guidance.

Third, in a fill-in-the-blank question, when creating an answer, by highlighting a portion that is important for deriving a correct answer in the question, a point serving as a point for deriving a correct answer can be seen at a glance. It is a hint for the person, and the efficiency of learning increases.

Fourth, in a calculation question, when creating an answer, by highlighting the items necessary for the formula for deriving the correct answer in the question, the items that are the points of the answer can be understood at a glance, and As a hint, learning efficiency will increase.
